User problem:
-----------------------------------
Discoverability of keyboard shortcuts is limited.
User need:
-----------------------------------
The user needs to be able to easily discover the
keyboard shortcut for specific actions.
Product requirement:
-----------------------------------
Create a short document outlining the shortcuts in
the IDE. Visualize the most important shortcuts.
Provide suggestions along the way (e.g. tooltips,
status bar hint, etc.)

I think docs is working on something like this already.
However, one suggestion:
Write some code that will generate a nice HTML doc
dynamically with all of the shortcuts in the IDE and
what they do.
On the welcome screen, in a visible way (or when the
user does something that could be done more efficiently
with a shortcut the first time?), offer to print a
"NetBeans quick reference card" from this document.
Hack factor: 0
Difficulty: 2 (out of 10)
Cookbook:
- Design of card
- Code to fetch all shortcuts
- Design for notification/integration w/ welcome screen
Issues:
- Where to get a good description? If not available in
a resource bundle, can that be changed for the future?
